Re: Back in the day ...
Went to a customer site to install an IBM 3274, earlier planning had ensured an underfloor 13amp socket was available. As I lifted a floor tile to connect the power lead I was informed a site electrician had to do all electrical work, union rules apparently. Leccy eventually arrived and proceeded to cut off the moulded plug with moulded ring pull on it to then try and install a cheapo bakerlite plug. The 3274 had a heavy duty screened cable which was not an ideal size for a standard 13amp plug but he managed it. I nearly offered to check his wiring but thought better of it, it worked fine anyway.
